NSFW What do men or women learn from porn?

I know that most people don’t use porn to teach them anything. However, I do believe that most people learn lessons from stories. The majority of porn generally depicts pretty much the same story over and over with only the actors or the settings being different. What is that story about?

The porn story, I believe is primarily a fantasy; a fairy tale just like Grimm Bros stories or Disney films. Fairy tales, like most stories, have morals. It may sound a little odd to ask this, but what is the moral of the porn story?

What do we learn from porn? Is it different for men and women? If so, how so. Does it affect people’s behavior? If so, how so.

Feel free to take on any or all of these questions.
